Racing Dynamics m20 e30 chassis headers

[RobDog]

The oil filter doesn’t need to be relocated. You can use a E30 M3 S14 oil filter. They are shorter and clear the headers. Because of the smaller size I change the filter more often or buy a quality filter. I will try to get a video with the top down so you guys can hear the beautiful sound these headers make. They bring a grin to my face every time I drive my mtech convertible.

I used the eta oil filter adapter and put the filter right on the block to eliminate the oil cooler. No issues, and the subject car made 157whp on an otherwise bone stock motor. Results are in the m20 dyno thread.

What is the real difference between a long tube header setup and an equal length setup? Hard to find real information about this topic. Do we have a stock dyno, long tube header dyno and equal length dyno to see where the power band changes?

I just found this today and remembered your question. It's not exactly what you're looking for but it might help. They're all from the same thread in 2010.

Are RD headers equal length?
Decent and good header gains (hp?)

I would be VERY interested in these, if they can be shipped directly from Italy to me...

US > EU taxes would kill me :(

Good point. EU > US taxes could kill this deal altogether.

Vote for your e30 :)

Please note that I am in Europe, so shipping from Europe to the US and back again would be silly- Not to mention the 30%+ tax that gets slapped on when it has to re-enter the EU. If we can avoid this I'd be game for a header.
